ltclailn: i

1. roller bearing coinprisinga series of rolls each consisting of a cylindrical radial load hearing'poi'tion and an enlargement at one end having;- oppcsitely beveled end tln'nh-t faces, nneiand Outer concentric annular race inenibei's each having :i radial and (DE), while the beveled faces (E3) and l load bearing portion engaging the cylinis beveled, a series of rolls surrounding said drical portions of said rolls` and respectively having oppositely beveled end thrust bearings engaging the opposite beveled faces of the rolls.

2. A roller bearing comprising a series of rolls each consisting of a, cylindrical radial thrust portion and an. enlargement at one end having oppositely beveled end thrust 'surfaces in proximity Vto each other being spaced merely b v the sloch required to transmit the thrnst;outer and inner parallel radial load bearing rare members, the one havingl a beveled end thrust bearing for engagement-i with the inner beveled faces of said rolls and the other race member having integral therewith a' beveled end thrust bearing for the outer beveled face of said rolls vthe'thrustbearing on saidfsleeve andan opposed beveled faee forengaging. the thrust bearing on said outer member, and a cage or retainer for holding said rolls in relation to said in'ner sleeve and forming therewith an organized'unit en'gageable With and disengageable from said outer bearing.`

4. A roller bearing comprising ,an inner cylindrical sleeve member having an annular groove in its outer face, one side of which sleeve, each having at one end an enlargement with opposite beveled faces engaging said groove and one of said faces bearing against the beveled face of the groove, a

cage for holding said rolls in spaced relation to each other and forming with said sleeve an organized unit, and an outer bearing member having a 'beveled end thrust bearing opposed tothe bevel bearing face of said sleeve. Y

5. A roller bearing comprisinga series of rolls each having a'cylindrical portion and an enlarged head at one end provided with oppositely beveled end thrust faces, an annular race member having a cylindrical face With which the cylindrical portions of said rolls engage, and a ,f beveled face complementary to the inner beveled faces of said rolls, vand a second annular race member having a cylindrical face engaging cylindrical portions of said rolls,'a beveled face engaging the outer beveled faces of said rolls, and anv integral connection between said outer beveled face portion and said cylindrical portion of -the last mentioned race member groovedv to provide peripheral clearance for the enlarged ends of said rolls.

6. A roller bearing comprising an annular outer race member having a-cylindrical face and an outwardly extending beveled portion at one end of said cylindrical face, a concentric inner annular race member hav- .ing a cylindrical portion opposite'the cylindrical portion of said outer member, -a grooved portion adjacent to said cylindrical portion and a portion beyond said grooved portion having a beveled face opposed to that on the first mentioned member, and a *series of rolls surrounding said inner race member having cylindrical portions for engaging the cylindrical portions of said race member andan enlarged head at one end having oppositely beveled faces complementary to the beveled faces of said race members and interposed therebetween toV transmit end thrust from the one race memv vhaving' a beveled portion complementary to and engaging the innerv beveled faces of said rolls and t-he other race member having an oppositely beveled portion complementary to and engaging the outer beveled faces of said rolls and an integral connecting portion between said outer beveled face portion 'and said cylindrical portion' of said last mentioned race member grooved to provide peripheral .clearance for the enlargements of said rolls.. l
